Burn dvd with .srt

Hey, I have a movie on my macbook, I dont have the original on disc.
I want to burn a dvd with subtitles to watch on my dvd. The movie is in .avi and subtitles .srt. The question.. Can I burn the dvd as data with the avi and rtf to play on my dvd (sounds stupid) -or- do I need a special software to do this (if I do please tell me which). I tried MacTheRipper as a forum here recommended but i see this only works with the original dvd. I searched other forums but all recommend pc software only. I know there's got to be software to do this on mac - please help!!
